Hello everyone I'm close to pulling the trigger and pre-ordering an antminer D3 and it would be for the December batch. I'm nervous that mining profitability will drop a ton by the time I'd receive the D3 and I'd be stuck not being able to reach ROI. Currently Dash is around $4k a month profit with the D3 after power costs.

With the increasing difficulty due to more D3s coming online how much should I expect profitability to drop by 2018?

I do realize it can mine other coins as well with the X11 algorithm so that may be an option if Dash isn't profitable anymore.

Personally, I do not want to think about Dash mining profit in 2018. Assuming the price is the same, the profit in Dec 2017 can be easily 15-20 times (or even more) less than now. That explain why D3 price now is so cheap.

I have a miner coming in batch 1a (the "second batch", which was miners that were reserved, but not paid, shipping September 18-25), and I'm kind of concerned about time for ROI. If the price stays the same, things will be ok, but given the number of miners flooding the market, and the volatility that coins have seen recently, I'm concerned. I know I'll reach ROI, but instead of being weeks, I think it will definitely be a month or more, and by next year, if the number of miners have been sold that people are speculating have been sold, it's possible that owning a single D3 will no longer be profitable on its own. I may be being pessimistic, but being a pessimist hasn't ever made me completely disappointed in the outcome.

This kind of investment can be named as playing lottery. If you are lucky enough, your ROI will be shorter. However, a lot players in the game, will reduce your chances to win lottery. If you trust your senses, you can play this game

If I were you, I would probably buy this antminer and started mining Dash. It is important to remember that sometimes it’s not about a monthly profit. For example, I strongly believe that by the time Dash Evolution is launched - the Dash coins will skyrocket.
